Night Vision Compatible Flashing Red LED Obstruction Beacon | FAA Compliant: L-864

Made in the USA flag

Compliance and Applications

FAA Compliant: L-864 Medium Intensity Obstruction Light
ICAO Annex 14 (Medium Intensity Type B & C)
Transport Canada CAR 621.19
DGAC of Mexico

Our FL-864LNV obstruction beacons combine the energy and cost saving benefits of LEDs with advanced technology to ensure reliable operation in all environments. The FL-864LNV is the most compact and efficient medium-intensity LED obstruction beacon on the market.

The FL-864LNV obstruction beacon is compatible with NVG and NVIS systems, making it the first true LED replacement for incandescent obstruction beacons. Night Vision Goggles (NVGs) and Night Vision Imaging Systems (NVIS) typically use filters that make common LED obstruction beacons invisible to pilots. Our obstruction beacon combines Red (620nm) and IR (850nm peak intensity) LEDs to ensure that obstructions marked with our beacons and side lights are visible to all pilots.

GPS Module Option

The GPS module is used to efficiently synchronize multiple beacons in locations where it isn’t practical to connect them by wire. Our module has a backup timing device to ensure that the lights remain in sync in the absence of a GPS signal. It also incorporates an advanced light sensor that ensures precise detection of ambient light levels, so your beacons always turn on when light conditions fall below FAA-specified levels.

Obstruction Lighting Controls

Lighting controls are designed for use when multiple obstruction light fixtures are to be controlled with common electronics. The electronic control module comes in a cast iron device box with threaded hubs on both top and bottom. Replacement modules (controls without device box) are also available upon request.

Obstruction Light Controller Model 81020


Model 81020 120VAC, 1000W photocell. FAA style photocells activate at 35 ft-cd and turn off at 58 ft-cd. A 45 second time delay prevents activation and de-activation from momentary light conditions. Does not come with device box, includes 1/2" threaded male fitting.

Obstruction Light Controller Model 81021
Model 81021 120VAC, 4800W photocell. Meets FAA/FCC requirements for obstruction lighting. Energized at 35 ft-cd and de-energized at 60 ft-cd. Time delay eliminates contact chatter. Contains dual 20A load contacts. Front plastic housing mounts to cast aluminum junction box (included).

Obstruction Light Controller Model 81022
Model 81022 Hazardous Location Photocontrol Unit. Outdoor lighting control for exterior lighting in hazardous locations: explosion proof, dust-ignition proof, and weatherproof. Nominal Voltage 50/60 Hz: 120/208/240/277. Voltage Range: 105-305. Housing: sand cast copper-free aluminum - epoxy powder coated.
